[application filed January 4, 1913. Serial E0. 21 0,3 34.

This invention relates to phonographs and is in the nature of animprovement upon the repeat mechanism (with certain novel features addedthereto) shown and described in my prior Patent No. 1,249,251. issuedDccemher 4, 1917. for improvement in phonographs.

One of the objects of the present invention to simplify and otherwiseimprove upon the repeat mechanism shown in my prior patent. Anotherobject is to provide simple and clficient means for controlling thenumber of times that the musical selection is repeated, and forautomatically stopping the mechanism when the piece has been playedthrough the predetermined number of times. Another object is to providea phonograph with controlled repeating mechanism actuated by the turntable-drive shaft or the phonograph. Another object is to provideimproved means in a repeat mechanism whereby record disks turn table orrecord of large or small diameter may he used.

Other objects and advantages will occur in the course of thisspecification and with all of said objects and advantages in view, thisinvention consists in the several novel features of construction,arrangement and combination of parts hereinafter full set forth and moreparticularly defined in the claims.

The invention is clearly illustrated iii-the drawings accompanying thisspecification in which:

Figure 1. is a. plan of the repeat mecha nism and u fragment of the lonearm and connections, the turn table having been removed trom the view;Fig". 2. is a view partly in side elevation and partly in vertical crosssection. taken on the line 2 2 of Fig. 1; Fig. 3. is a detail verticallongitudinal section taken on the line 3-3 of Fig. 1; Fig. '-'l. adetail vertical longitudinal section taken on the line 1 of Fig. 1; Fig.5, is a detail vertical section taken on the line 3-5 of Fig. 1; Fig.(3, is a detail horizontal section taken on the line ($6 of Fig. 4:;Fig. '4', is a detai Zontal section taken on the line Fig. 5; Fig. 8, isan end view oi the co mechanism shown in Fig. 4, looking iroin below;Fig. 9, is a detail vertical cro" tion taken on the line 9 9 in the 1.and 10. is a perspective vi or a slightly modified .lorm of theadjustment mechanism for accommodatino" the device for large and snuillrecord disi Referring to said drawings. the re character A de nates thetop of the p graph cabinet or case ordinary construction in which iscontained the usual motor. (a fragment of which is shown at B) foroperz'iting the phonograph. mechanism. in accordance with the usual andcommon prac tice, said motor drives a spindle or shaft 7, to which issecured a sleeve 8, that carries the turn table 9. The upper face theturn table usually provided with a Felt cover 10. and the usual spindle11, projects up from the table at its axis of rotation.

The tone arm 13. is rotatively mounted on a vertical axis. supported hvthe cahimvt in an suitable manner. and said tone arm overhangs the turntable as usual. is provided with an of theordinar v and well knownrcproducers 1%, which is liinn edlv connected to the tone arm by atubular bracket 15. which is pivotallv connected with the tone arm on ahorizontal axis. The stylus or needle 16. is employed in conuection withthe reproducer, as is common. and travels in a spiral groove in therecord disk 17. The horizontally swinging tone arm 13. is connected withthe horn or tune chamber in accordance with any of the well known waysand during the operation of the phonegraph, (While reproducing a musicalselection) the tone arm travels in the direction indicated by the arrowa. thereon in Fig. 1, whilethe disk itself rotates in the directionindicated by the arrow '5. thereon.

Secured to the tone arm is a bracket 19, which. in the embodiment of theinvention shown herein. projects down from. the lower end of the tonearm from a point near its vertical portion, and journaled in saidbracket is a spindle '22, which has an enlarged head 21, at one end,hearing against one side oi the bracket 19. and a pin or other crosspiece 21, at the other end of the spindle 22. holds said spindle againstendwise movement relative to the bracket. Fixcdly secured to saidspindle '22, is a frame shift sure, and when the rod 40 is turned toclamp the abutment member to the bar 38, this spring pressure isincreased, whereby the abutment member is firmly clamped to the bar. Theouter end of each rod 40", is bent at right angles to the main portionto provide a handle :0 whereby the rod portion l0, may be turned, andwhereby the abutment members may be adjusted back and forth upon theshift bar 337 In the case of the abutment member it), the rod 40, isshown as being somewhat longer than the rod 40, of the abutment member41, and it is shown as having its outer end rotatively supported in anear or bracket 38, which extends up from the base plate A It is obviousthat by turning either rod 40, to loosen the grip between the abutmentmember, and shift bar, the abutment member may be slid along the shiftbar 38, to vary the location of said abutment mem ber to therebyaccommodate record disks of diti'erent diameters. The roller carryingarm 23, moves between the abutment members e0, 41, and when it haspractically reached the limit of its movement in either direction itstrikes one or the other of the abutment members, depending upon whichdirection it is moving, and swings the lever 35, upon its fulcrum,thereby moving one of the supports L7, 47, into position where the plate42, or 43, may drop off the support into position to be engaged by oneof the shoulders 45, ,by the worm or screw 32 The control mechanism forcontrolling the number of times that the repeat mechanism is to operate,comprises a brake shoe 50, which is arranged to act upon the edge, ofthe turn table and arrest its movement by frictional engagementtherewith. in the form of the invention shown in, the drawing, saidbrake shoe 50, is carriedby a setting disk or dial 51, which isfrictionally connected with a toothed or ratchet wheel 52. The shaft orspindle 28, of the frame C, has a pawl or detent 53, upon its end whichis arranged to enter the notches between the teeth of the toothed wheel52, and to partially rotate said toothed wheel each time that the frameC, is shifted to the right, as viewed in Fig. I. Said pawl or detent 53,is here shown in the simple form of a crank arm upon the end of thespindle 23, and said crank arm is rocked back and forth each time thatthe frame. C. is turned upon its axis toraise and lower the track 27,and as a consequence, the toothed wheel 52. is advanced one step. Thefrictional connection between the setting disk or dial 51, and thetoothed wheel, may comprise a screw 54-, a stationarv plate 55, which ised to the top A of the cabinet, and supports the setting mechanism, awasher or spacing member 56, a knurled button or head 57, threaded uponthe upper end of the screw 54, and a spring washer 58, which is insertedbetween the toothed wheel 52, and a plate 55). The screw isnonrotatively ronnected with the plate 59, and the spacing member 56, isscrewed upon the screw 54, and turns therewith. By tightening up theknurled button or head 57, friction is created between the plate 59,spring washer 58, and toothed wheel 52; between the toothed wheel 52,stationary plate 55, and spacing member 56, and between said spacingmember 56, setting disk or dial 51, and knurled button 57. A pointer 60,is placed adjacent the setting disk or dial 51, and enables the usertoset the disk at any place along the numbered portion thereof to causethe repeat mechanism to repeat as many times as is desired. The numbersupon the disk or dial 51, correspond to the location and number ofnotches in the toothed wheel 52.

A shoulder 61, is provided upon one of the members of the settingmechanism and is here shown as comprising .a pin secured in the spacingmember 56, and said shoulder 61, is arranged to engage one arm of alever 62, pivotally supported on the top A, as at 63, with its other armin engagement with the shift bar 38. The shoulder 61, is located at sucha position that when the brake shoe 50, engages with the turn table tostop the same, the shoulder 61, engages the long arm of the lever 62.and draws the shift bar 38, toward the right, as viewed in Fig. 1.,thereby swinging the long end of the lever 35, toward the left andbringing the right, band edge of the elon ated slot 37", against theupstanding pin 37, thereby locking the parts until the setting disk isagain moved to set the mechanism for repeating.

Vhere an electric motor is employed instead of a spring motor fordriving the turn table, circuit breaking means may be employed forbreaking the motor circuit at the instant that the mechanism hasrepeated the predetermined number of times, and this circuit breakingmeans may comprise the plate 59, and two terminals (it, (it. which aresupported in position to contact with the plate 59. Said plate 59, mayhave :1 gap 65, located in position to register with the terminal 6i,and thereby break the circuit when the set-ting mechanism has reachedthe stop position it occupies when the brake 5t), fric tionally contactswith the turn table.

A slightly modified form f the adjustment mechanism for limiting therange of movement of the tone arm is shown in Fig. 10. In this'view, theshift bar is seen at 38 and the abutment at 41 which abutment cmnprisesa piece of wire bent to form an upstanding loop which grips the shiftbar 38 and a lengthwise extending portion 41 which terminates in coil 4Htwisted around the shift bar 38.
